ComOS 3.8.2 Release Note for PortMaster 3 98/12/30 Contents Introduction Bugs Fixed in ComOS 3.8.2 New Features in ComOS 3.8.2 Upgrade Intructions Technical Support Introduction The new Lucent InterNetworking Systems (formerly Livingston Enterprises) ComOS(R) 3.8.2 software is now released for the PortMaster(R) 3 Integrated Access Server. This release is provided at no charge to all Lucent customers. This release note documents commands and features added between ComOS release 3.8 and ComOS 3.8.2 on the PortMaster 3, including improved modem support. This release note applies only to the PortMaster 3. ComOS 3.8.2 is the last release supporting the old "True Digital V.34 Cards." Starting with ComOS 3.9, only the "True Digital 56K Cards" will be supported. Before upgrading, see "Limitations" for more information and thoroughly read "Upgrade Instructions." Back To TOP Bugs Fixed in ComOS 3.8.2 The following bugs have been fixed in ComOS 3.8.2. Improved Modem Support * A timing problem with V.32 modems is fixed. * A rate renegotiation and retrain issue with U.S. Robotics (USR) V.90 modems is fixed. * A disconnect problem that occurs when V.90 falls back to V.34 is fixed. * A timing problem with LT WinModems is fixed. * A USR V.90 "No Connect" problem is fixed. * A latency problem is fixed, improving ping times and reducing game latency. * A V.34 renegotiation issue is fixed (including the upstream part of V.90 and K56flex). * An A-law rate renegotiation problem is fixed. * The LAPM retransmitter in V.90 is improved. X.75 Large Frames X.75 on the PortMaster 3 now supports 2048 octet packets. In previous releases, the PortMaster 3 crashed upon receiving a large X.75 information frame (I-frame). Fractional E1 Channel Numbering Fractional E1 channel numbering is now correct. In previous releases, the channel numbering was off by one. For example, you had to specify channel 2 for channel 1 when configuring a fractional E1 line. Net5 Dial-Out When Inactive When using the Net5 ISDN switch type, the PortMaster 3 now attempts to activate Layer 2 if it is inactive during a dial-out attempt. In previous releases, if a Net5 ISDN switch initiated a Layer 2 inactive state, the PortMaster 3 did not activate Layer 2 again before attempting an outbound call, and the call failed. MFR2 Tones Conform to ITU Standards Multifrequency R2 signaling (MFR2) tone timing used in Interregister signalling phase or R2 is now in conformance with the ITU standards for MFR2 tones. In previous releases, MFR2 tones were sent for a fixed length of time. MFR2 Receive Threshold New receive thresholds now determine the sensitivity of the MFR2 tone detector. Microsoft Windows 95 and 98 Analog Multilink PPP Improved Throughput on an analog Multilink PPP (MP) connection from a Microsoft Windows 95 or Windows 98 machine has been improved. In previous releases, throughput was very poor when using analog MP from a Microsoft Windows 95 or Windows 98 machine. PMVision Password Backup PMVision 1.3 can back up the RADIUS and ChoiceNet(R) secrets, and user table passwords, from ComOS 3.8.2. The administrative password is not backed up. Static Routes Static routes are no longer overridden by OSPF routes. Large Syslog Messages Handled Correctly Memory is no longer overwritten by large syslog messages. System Block Leak Fixed The PortMaster 3 now discards malformed PPP packets containing only one byte of PPP data. In previous releases, receiving a malformed PPP packet that contained only one byte after escape characters were removed caused the PortMaster 3 to lose a system block. Reset after Lastcall In previous releases, a modem that entered the ADMIN state as a result of the use of the lastcall command required a 'set m0 off' and a 'set m0 on' to return it to the READY state. In this release only a 'set m0 on' is required. Back To TOP New Features in ComOS 3.8.2 No new commands or features have been added in ComOS 3.8.2. Upgrade Instructions You can upgrade your PortMaster 3 using PMVision 1.2, pmupgrade 4.0 from PMTools, or using the older programs pminstall 3.5.3, PMconsole 3.5.3, or PMconsole for Windows 3.5.1.4, or later releases. You can also upgrade using TFTP with the "tftp get comos" command from the PortMaster command line interface. *** CAUTION! If the upgrade fails, do NOT reboot! Contact Lucent *** *** InterNetworking Systems Technical Support without rebooting. *** The upgrade process on the PortMaster 3 erases the configuration area from nonvolatile memory and saves the current configuration into nonvolatile memory. Never interrupt the upgrade process, or loss of configuration information can result. This upgrade does not otherwise affect your stored configuration in the PortMaster 3. The installation software can be retrieved by FTP from ftp://ftp.livingston.com/pub/le/software/ and the upgrade image can be found at ftp://ftp.livingston.com/pub/le/upgrades: ComOS         Upgrade Image        Product _______         _____________     _____________ 3.8.2             pm3_3.8.2                PortMaster 3 Back To TOP Technical Support Copyright and Trademarks Copyright 1998 Lucent Technologies.
